Asymmetric encryption makes use of both a public key that is known to everyone and a private key, only known to the recipient. So, option A is the right one.
Asymmetric encryption, a type of cryptography, secures data by encrypting and decrypting it using two keys. For each pair, data is encrypted using a public key and decrypted using a private key. These keys are made by solving mathematical conundrums.
The most popular and reliable asymmetric encryption algorithm is RSA (Rivest Shamir Adleman). Increased data security is asymmetric encryption's key benefit. It reduces the possibility that scammers may find users' private information.
